Latex-assisted functionalized multi-walled carbon nanotube-reinforced elastomeric nanocomposites with enhanced mechanical performance

Functionalized multi-walled carbon nanotube (f-MWCNT)-reinforced elastomeric blend nanocomposites were developed through co-coagulation of natural rubber and poly (butadiene rubber) latex blends followed by efficient dispersion of f-MWCNT by using high-speed mechanical perturbation and probe ultrasonication. A systematic variation of f-MWCNT loading revealed superior mechanical properties up to certain loading level of nanofillers. Abrasion resistance was found to be affected by blend composition and nanofiller loading. The thermogravimetric analysis further revealed the thermal degradation behavior of the nanocomposites. Overall, our study has established the potential to develop high-performance elastomeric nanocomposites by using f-MWCNT, efficient dispersion technique, and appropriate process parameters.
